Ace polyethylene
tanks are designed to provide a safe and durable means for the containment
of approved chemicals providing that the tanks are handled, installed,
used and maintained according to the following guidelines. Consult
Den Hartog Industries concerning any questions regarding these guidelines.
Improper handling and installation can cause physical damage to
tanks, fittings, and accessories resulting in leakage and/or tank
wall failure. Improper use and maintenance can result in reduced
product life and leakage and/or tank wall failure. Failure to comply
with the following product guidelines will void all factory warranty.

1.
|
Upon
delivery, inspect the tank immediately for defects or shipping damage.
Any damage or discrepancies must be noted on both the driver's bill
of lading and your packing list. Claims must be made wiithin 30
days. Contact Sales Support at 1-800-342-3408 regarding the return
policy for damaged or defective products.

When unloading
the tank, avoid contact with sharp objects such as lift forks or
loader buckets that can cause damage, including tank wall puncture,
if the proper precautions are not observed. Never allow tanks to
be rolled over on the fittings. Large bulk storage tanks should
be unloaded with the use of a crane or another suitable lifting
device. Insure that the unloading area is flat and free of large
rocks, sharp objects or other objects that could damage the tank.
Avoid unloading the tanks in high winds. Always support or brace
tanks that are placed on their side to prevent rolling.

When selecting
the tank site, insure that the site is level and that adequate drainage
is provided for water runoff. The bottom of all tanks must be completely
supported. Reinforced concrete support pads are recommended for
tanks with capacities over 1000 gallons. In all cases, be certain
that the base material is designed to support the bearing capacity
requirements of the tank, including seismic and wind loads. If the
tank is installed in a stand or skid, note that the bearing capacity
requirements of the concrete or soil will be increased. Always anchor
the tank according to seismic or wind load zone requirements for
the site. Always consult with the applicable building codes governing
the tank site for specific support and anchoring requirements.

The only Ace Roto-Mold tanks designed
for burial are the septic and cistern tanks. Other tanks are not designed
to handle the pressure of surronding earth and should not be buried. |
|
5. |
Be certain
that the tank, fittings, and fitting gasket materials are compatible
wtih the chemicals to be contained and the anticipated storage temperatures.
Refer to the Chemical
Resistance Data Chart for the most commonly stored chemicals.
For applications not listed, consult the chemical supplier for storage
recommendations in polyethylene tanks, or consult Den Hartog Industries.

Tanks that will
be transported will require special consideration with regard to
the dynamic loads introduced by starting, turning or stopping the
tank and vehicle. Insure that the vehicle is designed for supporting
and braking the size tank selected, including the tank weight, capacity
and the specific gravity of the chemical to be transported.
Horizontal cylindrical
tanks, which are not free standing, must be fully supported around
the bottom of the tank diameter by not less than 1/3 of the circumference.
Freestanding tanks (tanks equipped with support legs) must be fully
supported under the legs and open sump areas and be installed with
hoops, which are securely anchored to a metal support skid. In all
cases, the tank skid or stand must be adequately fastened to the
vehicle bed to prevent shifting.

Be
careful not to over tighten poly fittings. If over tightened, these
fittings can be damaged and leak. In such cases, always replace
the fittings. If thread sealant is used, be certain that it is rated
for use with the chemical to be contained. Never subject fittings
to loads or weight that may cause cracking. Avoid rigid plumbing
from tank fitting. Fitting installations to and from tank must consider
the effects of expansion and contraction stresses due to temperature
as well as filling and emptying of the tank.
Caution:
Be particularly careful with fittings that are friction welded,
often referred to as "spinwelds". These fittings can fail
if attachments are not properly supported, are exposed to excessive
vibration or are over tightened. Never hang long lengths of hose
or pipe without support hangers to carry the dead weight of the
hose or pipe. Filters, valves and couplings will need to be supported
as well so the loads are not transferred to the "spinweld"
fitting. |
|
8. |
Never fill
a newly installed tank with chemical without first testing the tank,
fittings and installation with a non-hazardoues chemical such as
water. This procedure will also serve to rinse out the tanks and
connections. Test the installation at full capacity for a minimum
of 4 hours. |
|
9. |
All tanks must be vented for atmospheric
pressure as well as pressure created by filling and emptying the tank.
Never attempt to fill or empty a tank without adequate venting. |
|
10. |
The flat sides of rectangular or square
tanks greater than 18" wide or high must be securely supported
according to the specific gravity of the chemical stored and application
temperature. Support all tanks that are to be transported. |
|
11. |
Never install heavy equipment on the
tank walls. Consult the equipment manufacturer for recommendations
regarding installation on polyethylene tanks of the size selected. |
|
12. |
Submerged heaters must be installed
with a minimum of 4" of clearance from the tank walls. Never
allow the heater to contact the walls of the tank. Consult the heater
manufacturer for recommendations regarding installation of the heater
in polyethylene tanks. |
|
13. |
Insure that the tank walls are protected
from impacts, especially at temperatures below 40 degrees F. |
|
14. |
Warning: Do not walk on the tank
surfaces. Surfaces may be slippery. Serious injury or
death could occur. Always follow OSHA regulations when working
on or around tank systems. |
|
15. |
Warning:
Never enter a tank without first taking the proper safety
precautions. Serious injury or death or injury could occur.
Consult with the chemical supplier regarding recommendations as
well as the appropriate safety equipment required for handling the
chemicals to be stored. Always follow OSHA regulations when
working on or around tank systems.
|
|
| 16. |
Consult
the appropriate governing agency regarding secondary containment
requirements
for the tank selected and the chemicals to be contained. |
